FUEL-ECONOMIZER.

Application filed August 31, 1918.

To all whom it may concern:

Be it known that 1, JAMES P. MoMAHoN, a citizen of the United States, residing at Atlanta, in the countyof Fulton and State of Georgia, have invented new and useful Improvements in Fuel Economizers, of which the following is a specification.

This invention relates to an apparatus for consuming smoke and gases in furnaces using bituminous or anthracite coal and is particularly applicable to locomotive-fur-- naces. 1

The primary object of the invention is to provide a smoke consuming apparatus which will not only consume the smoke and other objectionable products of combustion, but will also appreciably multiply the heat units and operate to minimize the consumption of fuel, and is an improvement on a patent granted to me March 6, 1906, and numbered 814,230.

In practice it has been found that a mixture delivered directly to the fire box will be consumed by the fire therein before consuming the products of combustion and it is therefore the object of the present invention to overcome this objectionable feature by delivering a hydro-carbon mixture upon a baflle wall located in the fire box in the path of the product of combustion, thereby vaporizing the mixture for ignition by said products, so that the latter will be wholly consumed by the combustion of the hydrocarbon mixture.

Another object of the invention is to deliver the mixture from the burners or nozzle in a preheated state, so as to render the same more readily vaporized.

A still further object of the invention is to provide an apparatus of the class specified which may be easily applied and having athoroughly reliable and efficient operation.

Other objects and advantages of the in vention will appear as thefollowingdescription is read in connection with the accompanying drawings.

In the drawings Figure 1 is a view illustrating the application of the invention to the fire box of a locomotive, the latter being "shown by dotted lines' Fig. 2 is a fragmentary sectional plan of the invention;

Fig. 3 is an enlarged sectional View through one of the burners or nozzles;

Specification of Letters Patent.

Serial No. 252,278.

As in the patent above mentioned, the invention aims to interpose between the products of combustion and the smoke box. a wall or diaphragm constituting a wholly combustible hydro-carbon mixture which entirely cuts off. turns back, and wholly consumes said products in its own combustion. In the before mentioned patent the mixture was supplied directly to the fire within the fire box, but in order to prevent the consumption of the mixture by the products of combustion before the latter are consumed, the mixture is delivered to a battle-wall located in the fire box in the path of the products of combustion, the latter heating the wall to a high temperature so as to vaporize the mixture, which is readily ignited by the products of combustion so as to wholly consume the said products in the combustion of the mixture.

In the drawings, the numeral 10 indicates the fire box of a locomotive boiler, the fiues of the boiler being shown at 11 and a flue sheet at 12, while the smoke box of the locomotive is indicated at 13.

The locomotive carries an oil tank or reservoir 14 herein shown as mounted upon the top of the boiler, but it is of course understood that this tank or reservoir may be located at the most convenient point. Leading from the tank or reservoir 14 are pipes or conduits 15, which extend longitudinally of the boiler upon the outside thereof and enter the smoke box 13. Located in the smoke box are suitable preheating devices 16, which communicate with and receive the oil or other fluid contained in the tank or reservoir 14. The pipes 16 extend from the opposite side of the preheating devices 15 and communicate with burners or nozzles 17, the latter being provided With a plurality of restricted outlet passages 18 and 19. The latter passages communicate with a mixing chamber 20, which surrounds the nozzles 17 and receives dry steam from a source 21 located in the cabin of the locomotive, the said source communicating with the chamber 20 through the medium of a supply pipe 22, which is controlled by a valve 28.

Any number of nozzles or burners may be employed there being two shown in the present instance. These nozzles extend through the flue sheet of the boiler into the fire box 10, the pipes 15 and 22 passing through the boiler fines, so that the mixture which consists of. crude oil and kerosene and dry steam may be delivered directly into the said fire box.

The mixture is delivered in a preheated state due to the location of the device 16 within the smoke box of the locomotive, but it is desirable that this mixture be vaporized so as to render it more readily combustible and for this purpose the mixture is delivered to a .baffle wall 23 located in the fire box and spaced from the flue sheet, the said wall being located directly-in the path of the products of combustion from the fire box.

As in my previously mentioned patent, the mixture is discharged or projected in the form of a hollow cone or column into the fire box between the products of combustion and the open ends of the flues, so as to provide a wall or barrier to prevent the passage of the said products through the fines, but instead of being delivered directl from the pipe is delivered upon the baflie Wall 23, to vaporize the mixture and to rechanges in its form, proportions and minor 5 details of construction and the right is reserved to make such changes.

Having described the invention, What is claimed is In a fire-box an angular bafile dividing the fire-box into a primary combustion chamber and a secondary combustion chamber, the upper portion of said baflle being inclined upward over said primary combustion chamber, a nozzle extending into said secondary combustion chamber and arranged to discharge fluid fuel against the inclined portion of the baflle in a direction opposite to the flow of the products from the primary combustion chamber.

In testimony whereof I aflix my signature.
